Quote from usedbookbrothers .... on 06/12/08:
"The P-11 does not have a free-floating firing pin, right ? ...Well, I had the
slide locked in the out-of-battery position this evening, and noticed that
when Ibturned the gun muzzle-downward, the firing pin drops down and
protrudes about 5 mm from its well. ... Is it supposed to do this?"
.
Response: " Jeremiah, no it is not supposed to do this.
I do believe you have a broken firing pin spring. . It's function is to
hold the firing pin BACK to prevent slam fires & drop fires. …."

This is one case where the firing pin system became unsafe on its own.
For a detailed article on slamfire, see http://en.wikipedia.org/wiki/Slamfire

Another example of firing pin risk: a recall notice for a semi pistol
warning about installing the firing pin "upside down". (EAA Witness-style
semi-auto pistol with serial number AE00000 to AE70000)
("immediately field strip the pistol and send the slide assembly to
European American Armory Corp. … will replace the original firing
pin with an upgraded firing pin for your pistol.")
